+// The class SuperEngine is a super class for engines that produce moves.
+// It implements functionality that move engines have in common, which is
+// useful if you want to use several different engines in the same program
+// (for instance when you are test playing different strategies against each
+// other).
+//
+// SuperEngine implements:
+//
+// Random number handling (engines should not play exactly the same games
+// repeatedly).
+//
+// Setting playing strength level.
+//
+// Functionality for telling the engine to interrupt calculation.
+//
+
+// Public and protected functions:
+
+// public SuperEngine(int st)
+// Creates an engine playing at level st. All integers greater than 0
+// should be possible levels. There need not be any actual difference in
+// playing strength between levels, but if there is, higher number should
+// mean greater playing strength.
+
+// public SuperEngine(int st, int sd)
+// The same as above, but uses sd as the seed for the random generator.
+// This means that the engine always behaves in exactly the same way
+// (practical when testing).
+
+// public synchronized final void SetInterrupt(boolean intr)
+// This function could be called when ComputeMove() (see below) is
+// executing. It tells the engine to interrupt calculation as
+// soon as possible and return null from ComputeMove().
+
+// protected synchronized final boolean GetInterrupt()
+// Returns true when SetInterrupt() has been called. Should be called
+// with short intervals from ComputeMove().
+
+// public void SetStrength(int st)
+// Sets playing strength level.
+
+// public int GetStrength()
+// Gets playing strength level.
+
+// public void SetSeed(int sd)
+// Changes the random seed.
+
+// public abstract Move ComputeMove(Game g)
+// This function should produce a move. If SetInterrupt() is called
+// during its execution it should return null as soon as possible.
+
+// Protected members:
+
+// protected int m_strength
+// Is set and read by SetStrength() and GetStrength().
+
+// protected Random m_random
+// Could (and should in a good engine) be used to prevent the engine from
+// repeating itself, always playing the same moves in the same positions.
+// If this is not done, winning once would make it possible to play the
+// same moves and win every time against the program.
